Got beam at about 7:00 pm.

have been taking unpolarized data both deuterium and hydrogen.

Deuterium data are taken to look for nutrons in neutron bars.
Unfortunately, current ntuple.C does not really fit the need. nc.C was
created with slight change from ntuple.C to cut out the data triggered by:
one TOF and one NC on the opposite sector. results are written into a root
file called edp-????.root.

Hydrogen data were taken to calibrate a few bars of scintillators Ben
installed on the backward angle to look for large backward angle
scattering events.

had some problem with spuds. reaction was extremely slow, could not fine
/net/data/1/, rebooted spud 1, changed to /net/data/4, seemed to fix
things. However, connection from dblast07 was still slow.
